Collision detection and estimation from a monocular visual sensor is an important enabling technology for safe navigation of small or micro air vehicles in near earth flight. In this paper, we introduce a new approach called expansion segmentation, which simultaneously detects “collision danger regions” of significant positive divergence in inertial aided video, and estimates maximum likelihood time to collision (TTC) in a correspondenceless framework within the danger regions. This approach was motivated from a literature review which showed that existing approaches make strong assumptions about scene structure or camera motion, or pose collision detection without determining obstacle boundaries, both of which limit the operational envelope of a deployable system. Expansion segmentation is based on a new formulation of 6-DOF inertial aided TTC estimation, and a new derivation of a first order TTC uncertainty model due to subpixel quantization error and epipolar geometry uncertainty. Proof of concept results are shown in a custom designed urban flight simulator and on operational flight data from a small air vehicle.

A design and proof of concept of a new type of WLAN, complete with simulation and results from the simulation has been described. Each AP Node is implemented as a self-contained embedded OS unit, with all algorithms resident in its Operating system. The normal day-to-day functioning of the AP node is based entirely on resident control algorithms. Upgrades are possible through a simple secure communications interface supported by the OS kernel for each AP node.

This invention discloses a method for communications faster than the Nyquist rate (FTN) and faster than the Shannon rate which method is Quadrature Layered Modulation (QLM). QLM properties include scaling the data symbol pulses to maintain the same error rate performance for all rates. QLM alternatively considers the increase in the data symbol rate to be a layering of additional communications over the same link. The Shannon bound is a limit on the capacity of a communication link when transmitting data symbols at the Nyquist rate. QLM observes one can communicate at FTN to transmit more information than the Shannon rate since the Nyquist rate captures the information in a frequency band and does not constraint the information. These properties describe QLM and a separate math proof-of-concept is disclosed. Implementation and performance data demonstrate QLM can support communications data rates which are at least double the Shannon rate.

When interacting and talking with each other, humans are quite successful at conveying information and reacting appropriately. That is, they are able to interpret situational information which in most cases is only implicitly given. This ability is in stark contrast to most of the current state-of-the-art computer and telecommunications systems, which in large are unaware of this context information. Consequently, there has recently been great interest in making applications more context-aware so that they can adapt to different situations and be more receptive to user's needs.The purpose of this project was to explore how one through examining different kinds of context information can find ways to automatically set a user's presence status. This presence status is useful as it allows for a person to decide whether it is appropriate to initiate communication or not. Further, it was the mission of this project to review how a policy-based approach could be use together with the mentioned aggregated presence status to increase user personalisation of communication. Finally, the project set out to show how one can model and implement such a context-aware system using Ericsson's service creation framework; ServiceFrame.The project used a model-driven approach (MDA) in which most of the effort went into modelling the functionality of the system using formal UML2.0 models and then transform these into code using code generation tools and MDA viewpoints. During the modelling of the system, it was decided to examine user's context information and from this classify the user's aggregated presence status by utilising a supervised learning classifier. In a proof-of-concept solution, the probabilistic classifier, Naïve Bayes, proved to be an extremely fast and accurate classifier which should be considered as a strong option in any future implementations of the system. Personalisation of communications by design was achieved both through allowing completely personal classification rules, as well as through a policy approach. This policy approach consisted of letting a user construct a personal prioritising of his or hers terminals based on his or her aggregated presence status. It is suggested to expand this approach by also taking the group membership of the entity which requests the user information into account.Using supervised learning makes sure the system is not to be solely dependent on any particular context data sensor but rather having the ability to adapt to an ever-changing environment. With the expected explosion of context sensors in areas such as ubiquitous computing [15], this ability to adapt will become increasingly important in future context-aware systems. In addition to this flexibility, the use of supervised learning also introduces the ability to classify completely unknown scenarios. This means that even if the classifier encounters a new scenario which is has never seen before, it tries to predict a status based on the underlying previous data. It stated that these predictions often have a high degree of accuracy with the right training data.The system used the agent oriented architecture, which it is stated has a good support for personalisation as agents generally are used to represent entities in the real world (e.g. users). Through this approach, the system allows for a completely personal classification of a user's current context. By doing so, it is acknowledged that pre-defined rules does not fit everyone, but should be adapted to give each person a high degree of personalisation.

The invention discloses a method and an apparatus for keeping proof of concept (PoC) continuous connection handling capacity.

Emerging evidence indicates that diminished activity of the vasoprotective axis of the renin-angiotensin system, constituting angiotensin converting enzyme2 (ACE2) and its enzymatic product, angiotensin-(1-7) [Ang-(1-7)] contribute to pulmonary hypertension (PH). However, clinical success for long-term delivery of ACE2 or Ang-(1-7) would require stability and ease of administration to increase patient compliance. Chloroplast expression of therapeutic proteins enables their bioencapsulation within plant cells to protect from acids and gastric enzymes; fusion to a transmucosal carrier facilitates effective systemic absorption. Oral feeding of rats with bioencapsulated ACE2 or Ang-(1-7) attenuated monocrotaline (MCT)-induced increase in right ventricular systolic pressure, decreased pulmonary vessel wall thickness and improved right heart function in both prevention and reversal protocols. Furthermore, combination of ACE2 and Ang-(1-7) augmented the beneficial effects against cardio-pulmonary pathophysiology induced by MCT administration.Experiments have also been performed which indicate that this approach is also suitable for the treatment or inhibition of experimental uveitis and autoimmune uveoretinitis These studies provide proof-of-concept for a novel low-cost oral ACE2 or Ang-(1-7) delivery system using transplastomic technology for pulmonary and ocular disease therapeutics.

Advances in technology and the availability of low cost sensors have led to an unprecedented growth in the volume of spatial data. Unfortunately, the time required to evaluate even simple spatial queries over large data sets greatly hampers the ability to interactively explore these data sets and extract actionable insights. While modern hardware (such as Graphics Processing Units or GPUs) are increasingly being used to speed up spatial queries, existing solutions have two important drawbacks: they are often tightly coupled to the specific query types they target, making it hard to adapt them for other queries; and since their design is based on CPU-based approaches, it can be difficult to effectively utilize all the benefits provided by the said hardware. To overcome these issues, spatial data are represented as geometric objects and a set of composable operators that operate over these objects are defined. The expressiveness of the proposed representation is demonstrated by realizing standard spatial queries as a composition of the proposed operators. To illustrate the performance gains that can be attained, a proof-of-concept GPU-based implementation focusing on a subset of the operators was built and evaluated.

The electrolysis of cuprous chloride was carried out in the electrochemical cell. The particle size, current density, cathodic current efficiency, conversion of cuprous chloride and yield of copper formed depends strongly on current flow, heat transfer and mass transfer operation. The current flow, heat transfer and mass transfer are depends on surface area ratio of anode to cathode, distance between electrodes, concentration of HCl, applied voltage, flow rate of electrolyte, CuCl concentration and reaction temperature. The electrolysis of cuprous chloride as a part of Cu—Cl thermochemical cycle for hydrogen production is experimentally demonstrated in proof-of-concept work.

Disclosed are a method for achieving ultrahigh spectral resolution and a photonic spectral processor, which is designed to carry out the method. The disclosed photonic spectral processor overcomes the current 0.8 GHz spectral resolution limitation. The new spectral processor uses a Fabry-Perot interferometer array located before the dispersive element of the system, thus significantly improving the spectral separation resolution, which is now limited by the full width at half maximum of the Fabry-Perot interferometer rather than the spectral resolution of the dispersive element spectral as is the current situation. A proof of concept experiment utilizing two Fabry-Perot interferometers and a diffractive optical grating with spectral resolution of 6.45 GHz achieving high spectral resolution of 577 MHz is described.

Optogenetic and chemogenetic actuators are critical for deconstructing the neural correlates of behavior. However, these tools have several drawbacks, including invasive modes of stimulation or slow on / off kinetics. These disadvantages have been overcome by synthesizing a magnetically sensitive actuator, Magneto, comprised of the cation channel, TRPV4, fused to the paramagnetic protein, ferritin. Magneto permits non-invasive magnetic control over neuronal activity by showing remote stimulation of cells using in vitro calcium imaging assays, electrophysiological recordings in brain slices, in vivo electrophysiological recordings in freely moving mice, and behavioral outputs in zebrafish and mice. As proof of concept, the first magnetogenetic control of the nervous system was demonstrated by using Magneto to delineate a causal role of striatal dopamine receptor 1 neurons in mediating reward behavior in mice. Together, our results present Magneto as a novel actuator capable of remotely controlling circuits associated with complex animal behaviors.
